To investigate the computed tomography (CT) characteristics of adrenal ganglioneuromas (AGNs) and to determine the ability of CT scanning to distinguish between large (>3 cm) and small (≤3 cm) AGNs.
This retrospective study searched the electronic medical record system of a hospital between January 2008 and July 2019 in order to identify patients with pathologically-confirmed AGNs that underwent three phases of CT scanning. The CT features were compared between large and small AGNs.
A total of 30 patients with pathologically-confirmed AGNs were included in the study. The majority of patients (76.7%; 23 of 30) were asymptomatic and there were nonspecific symptoms in seven patients. The 'pointed peach' sign appeared in more than half of the patients (53.3%; 16 of 30). The CT value of the arterial phase, progressive enhancement, morphology and calcification in the CT images were found to be significantly different between large and small AGNs. Progressive enhancement was more likely to occur in small AGNs. Most large AGNs had irregular shapes, while small AGNs were likely to be round or oval with a smooth border. Calcifications were noted in large AGNs (42.9%; six of 14).
CT scanning can show many of the key imaging characteristics of AGNs used to distinguish between large and small AGNs.
探讨肾上腺神经节细胞瘤（AGNs）的计算机断层扫描（CT）特征，并确定CT扫描区分大（>3 cm）、小（≤3 cm）AGNs的能力。
本回顾性研究检索了某医院2008年1月至2019年7月的电子病历系统，以识别经病理证实且接受了三期CT扫描的AGNs患者。比较大、小AGNs的CT特征。
本研究共纳入30例经病理证实的AGNs患者。大多数患者（76.7%；30例中的23例）无症状，7例有非特异性症状。超过半数患者（53.3%；30例中的16例）出现“尖桃”征。发现大、小AGNs的CT图像在动脉期CT值、渐进性强化、形态及钙化方面存在显著差异。渐进性强化更易发生于小AGNs。大多数大AGNs形状不规则，而小AGNs多呈圆形或椭圆形，边界光滑。大AGNs中有钙化者占42.9%（14例中的6例）。
CT扫描可显示AGNs用于区分大、小AGNs的许多关键影像特征。
